| Abstract(in English) | Emotional visual images, such as those of facial expressions and evolutionally determined threats (e.g., spiders and snakes), have been known to cause behavioral, psychophysical and neurophysiological responses without subjective experience. In this experiment, we examined whether the previously reported influence of the non-consciously perceived emotional visual images, which were produce by either presenting the visual stimuli in the blind field of a blindsight patient or using visual masking techniques, would also occur in normal subject. To this end, we created non-conscious perceptual state using binocular rivalry and see if the emotional visual images that were suppressed in binocular rivalry could influence the visual detection of facial expressions. Observers were asked to press a button as fast as possible after detecting the face that expressed the target emotion (happy or anger). We presented a task-irrelevant prime face (happy, anger, or absent) shortly before and in the opposite visual hemi-field of the target face. The priming face was suppressed using the continuous flash suppression technique. The results showed that even when the observers barely noticed the facial expression of the suppressed prime face, the reaction time was significantly slower when the facial expressions of the suppressed prime and dominant target were incongruent and when the suppressed priming face expressed anger. These results indicate that facial expressions are processed in the absence of the perceptual experience even in normal subjects. |
